v3.7 (unreleased)
    * Fix atomic saves to avoid garbling config and data files if the disk is full.
    * Convert the `friendly-name` boolean to the new `name-format` setting.  This allow users to customize how the friendly name is constructed.
    * Demote guessed encodings logs from 'error' to 'warning'.

v3.6 (2013-09-09)
    * Fix missing port argument for IMAPAuthenticationError.
    * Fix `<div id="entry>` syntax error in HTML mail.

v3.5 (2013-06-05)
    * Added digest generation and post-processing hooks.
    * Fix html2text configuration (ignored since 2012-10-04).
    * Fix opmlexport crash due to orphaned feed data.
    * Use feed names in OPML 'text' attributes.

v3.4 (2013-05-14)
    * Added post-processing hooks for user-specified message manipulation.
    * Added settings for IMAP delivery.  The old `use-smtp` boolean has been replaced by a new `email-protocol` setting.  Non-IMAP users should adjust their configuration to set `email-protocol` to either `sendmail` or `smtp`.

v3.3 (2013-04-13)
    * Fix SMTP message submission logic.
    * Fix error inheritence (super() calls).
    * Convert html2text parsing errors to `ProcessingError`s.

v3.2 (2013-03-13)
    * Use extended interpolation in configuration files, to allow percent signs (%).
    * Added .as_string() fallback to email flattening (only used if `use-smtp = False` and `use-8bit = True`).
    * Added sendmail configuration option.  Change this if you want to use an alternative, sendmail-compatible mailer.

v3.1 (2013-02-14)
    * Import __url__, __author__, and __email__ in rss2email.error, which fixes bugs in formatting a number of errors.

v3.0 (2013-02-13)
    * Changed project email (rss2email@tremily.us) and homepage (http://github.com/wking/rss2email).

    * Converted the command line interface to argparse, with some restructuring along the way.
    * Added the r2e.1 man page (based on one from the Debian package).

    * Added Message-ID headers to outgoing email.
    * Added a test suite.
    * Upgraded to Python 3.2 to take advantage of cleaner Unicode handling and argparse.
    * Require Signed-off-by lines in new commit messages, following the Linux and Git projects.

v2.64 (2008-10-21)
    * Bug-fix version
        o Gracefully handle missing charsets
        o Friendlier and more useful message if sendmail isn't installed
        o SunOS locking fix

v2.63 (2008-06-13)
    * Bug-fix version and license change:
        o Licensed under GPL 2 & 3 now
        o Display feed number in warning and error message lines
        o Fix for unicode handling problem with certain entry titles

v2.62 (2008-01-14)
    * Bug-fix version:
        o Simplified SunOS fix
        o Local feeds (/home/user/file.xml) should work

v2.61 (2007-12-07)
    * Bug-fix version:
        o Now really compatible with SunOS
        o Don't wrap long subject headers
        o New parameter CHARSET_LIST to override or supplement the order in which charsets are tried against an entry

        o Correctly handle international character sets in email From

v2.59 (2006-06-09)
    * Finally added oft-requested support for enclosures. Any enclosures, such as a podcast MP3, will be listed under the entry URL
    * Made feed timeout compatible with Python versions 2.2 and higher, instead of v2.4 only

    * Improved empty feed checking
    * Improved invalid feed messages
    * Unfortunately, rss2email is no longer compatible with Python v2.1. Two of the most serious lingering issues with rss2email were waiting forever for non-responsive feeds and its inablility to properly handle feeds with international characters. To properly fix these once and for all, rss2email now depends on functionality that was not available until Python v2.2. Hopefully this does not unduly inconvenience anyone that has not yet upgraded to a more current version of Python.

v2.58 (2006-05-11)
    * Total rewrite of email code that should fix encoding problems
    * Added configurable timeout for nonresponsive feeds
    * Fixed incorrectly using text summary_detail instead of html content
    * Fixed bug with deleting feed 0 if no default email was set
    * Print name of feed that is being deleted

v2.57 (2006-04-07)
    * Integrated Joey Hess's patches
       o First, a patch that makes delete more reliable, so it no longer allows you to remove the default email address ('feed' 0) and thereby hose your feed file, or 'remove' entries that don't exist without warning; and so it only says IDs have changed when they really have. Originally from http://bugs.debian.org/313101
       o Next a patch that avoids a backtrace if there's no email address defined, and outputs a less scary error message.
       o Next, a simple change to the usage; since the "email" subcommand always needs a parameter, don't mark it as optional.
       o And, avoid a backtrace if the email subcommand does get run w/o a parameter.
       o And also avoid backtraces if delete is run w/o a parameter. Also adds support for --help.
       o Simple change, make a comment match reality (/usr/sbin/sendmail)
       o This avoids another backtrace, this time if there's no feed file yet. [load()]
       o Add a handler for the AttributeError exception, which feedparser can throw. Beats crashing..
       o Next, four hunks that make it more robust if no default email address is set and feeds are added w/o an email address. This patch originally comes from http://bugs.debian.org/310485 which has some examples.
       o Finally, this works around a bug in mimify that causes it to add a newline to the subject header if it contains very long words. Details at http://bugs.debian.org/320185. Note that Tatsuya Kinoshita has a larger patch torard the end of that bug report that deals with some other problems in this area, Aaron has seen that patch before and said it "looks pretty reasonable".
    * add() catches error case on first feed add and no email address is set
    * Made "emailaddress" consistent param label throughout
    * Error message improvements
    * Deleted problematic "if title" line
    * Deleted space in front of SMTP_USER
    * Only logs into SMTP server once
    * Added exception handling around SMTP server connect and login attempt
    * Broke contributors across multiple lines

    * SMTP AUTH support added
    * Windows support
    * Fixed bug with HTML in titles
